Application June 24,

6 Claims.

My present invention relates to the art of dispensing devices and more particularly to a canned oil dispenser.

There is a marked insistence on the part of 51- many motorists for lubricating oil that is pack-- aged byits producers and sold in sealed, tin containers. In this way the consumer knows that he is getting exactly the oil specified. by the maker of his car for the condition and mileage of his car. This insistent demand has made desirable a dispenser that will conveniently drain the oil from the can into the crank-case of the car. Many devices have been produced for this purpose; however, they have been characterized by certain deficiencies such as the difficulty of their operation; the fact that the dispensers themselves, in many instances, retain undispensed a certain amount of oil that is mixed with the next can of oil opened which may be of 20. a difi'erent character. Further, the devices observed have often been diificult to operate or required that the can be punctured by a sepa.

rate device and then brought out to the car and inverted into a funnel or some such arrangement. This method of operating often leads the service station operation into difiiculties; particularly when a motorist may change his mind, for instance, on the exact weight of oil that he desires, or when there may have been a misunderstanding between the car owner and the station operator.

With my present dispenser I provide means which can be very easily operated by a youth, a woman, or anyone not particularly skilled in that type of operation; and one which operates with certainty, which cuts the dispensing opening and the vent opening with ease and by a single operation at the instant just before the oil is to be drained into the crankcase. In some instances a third puncture is provided for in the side of the can.

The principal object therefore of my present dispenser is to provide a convenient and easily operated means for draining the contents of a .container into the crank-case of a car.

A further object of my present invention is to provide a device for dispensing oil that by its very nature can be very economically constructed to the end that it may bev sold cheaply, and can be expected to give long periods of satisfactory service.

Still another object of my present invention is to provide a dispenser with a spout attachment and general construction that admits of easy servicing of any of the known makes of cars.

Other and more specific objects will be apparent from the following description taken in connection with the accompanying drawings, wherein Figure 1 is a perspective View showing a liquid dispenser made after the teachings ofmy present invention.

Figure 2 is a perspective View showing the dis pensing, or draining, opening cutter together with the fulcrum used in the operation of my device.

Figure 3 is a perspective showing the means employed for making the vent opening and, where required, in making the body puncture for purposes of defacing the oil container.

Figure 4 is a top plan view of the dispenser. of Figure 1.

figure 5 is a side elevation of my dispenser, certain parts of which are shown in section, with a can in place ready for opening which can, itself, is shown in section.

Figure 6 illustrates, in perspective, the vent puncture produced by my device.

Figure '7 illustrates, in perspective, the dispensing, or draining, opening as formed in a tin container together with a body puncture.

Figure 8 is a view similarto Figure 5 excepting that the can is shown as open-ed, in its'dispensing position, with the spout also shown in its dispensing position.

Referring to the drawings, throughout which like reference characters indicate like parts, I'll designates the body of my dispenser. This should be made of a size that will have sufiicient capacity to accommodate the full volume of the can of liquid to be dispensed; This makes it possible to use the same without danger of over flowing as may occur if there should be any reason for stopping the dispensing after the can is opened. The dispenser is preferably formed with a tapering body, or at least a tapering upper portion so that the two positions of the can, that before it is opened and the one after it is opened, readily can be accommodated. Also conveniently arranged is a suitable handle as I'Z which is normally secured to body ID as by riveting the same thereto.

Disposed somewhat up from the bottom of body I t is the bottomproper 14. This I prefer to form as a separate member which can be formed by pressing, or forming, and then securing it in position by some convenient means such as welding, soldering, or riveting. The principal requirement of bottom I 4 is that it be so arranged as, for instance, after the showing of Figures 5 and 8, that all the oil Will drain from the body of container l0 when a can of oilis being dispensed.

Then too, as a matter of convenience, so that the device will sit level when not in use, I prefer that the discharge as it be so arranged that it comes out through the side wall of container E0 as is illustrated at II. In this way the lower rim of the container proper will form a plane and serve as a rest for the device. Attached to outlet I6 is a section of flexible tubing W. This is desirable first, to provide means for starting or stopping the flow of oil after the showing of Figures 5 and 8, where the two positions of the spout are clearly shown; and, secondly, to provide flexibility in the discharge spout so that inaccessible or unusual filling openings can be easily reached. Secured to the end of the flexible tubing it I prefer to provide a section of solid tubingtt having at its extreme end a-downwardly tinned discharging spout 2 i. This arrangement provides for the greatest ease of operation and cleanliness in that the smooth tubing 2!) can easily be wiped clean, although it normally will run clean. This is not true of the usual flexible tubing as shown at it.

The spout assembly consisting of members l8 and 20 are held in position by preferably two tension springs l9; these are secured by suitable means to both the can body and the spout and, act as toggle springs; when the device is in its upper position as shown in Figure 5 these springs tend to raise it still further and when, in the lowered position of the spout, as shown in Figure 8, the springs again tend to maintain the spout in its depressed position.

Secured within body it above the bottom it is the main opening cutter and fulcrum illustrated probably best in Figure 2. This consists of the opening member proper 22, which is provided with a down-turned portion as at 2t and another down-turned portion at 25. These form a means for attaching the cutter to the body Hi. This attachment may again be by any convenient means, in the drawings I have illustrated riveting, although it will be apparent that soldering, brazing, or welding might be employed. The support member 26 is formed by striking the same out of the center of member 22 so as to provide an opening at 2?.

Secured also to member 22 is a rest or ful crum member at; this I prefer to form with an upturned edge at 31 to form the actual fulcrum, two down-turned portions 32 and 33 which provide means for attaching the same to the body iii.

Secured to body it preferably by the same means that secures leg 24 of member 22, is the venting member 35. This member consists essentially of a resilient, preferably spring stock strap 36 which is secured to body ill and has at its upper end the venting point 38. This point is further provided, preferably, with a groove as at 39 so as to with certainty provide a free passage for the entry of air into the can as the oil is being dispensed. It has often been found that there is a requirement that the can body itself be mutilated so that the can cannot again be used. To provide this puncture I have shown an auxiliary point at Mi which will puncture the can in its body portion.

Method of operation In using my dispenser the first operation is to place the tin can in the container body after the showing of Figure 5. When so placed the lip or rim 33 of the can $2 is so placed as to engage lug i l formed as'part of member 22. The can is tilted naturally to the left as viewed in Figure .3 by virtue of itsresting' on point 28. Inthis position member 36 is displaced to the left as shown in Figure 5 with point 38 above but not engaged in the top of the can. With the can so placed the next operation is totake the dispenser and the can to the point where the liquid or oil is to be used. The spout assembly is now depressed against the tension of springs l9 until they pass their center of action and then tend to pull the spout still lower as is shown in Figure 8, and spout 2! is entered in the filling opening. The operator then moves the top of the can to the right as viewed until it assumes the position shown in Figure 8. Here it will 'be observed point 23 has entered far into thebottom of the can providing the discharge or dispensing opening 46; at the same time point 38 has pierced the top of the can at t8 and air is free to flow in through groove 39; also if the device is provided with the mutilating point 40 it will have pierced the body of the can, as at 50.

In order to bring about sufiicient displacement of can d2 so as to bring point 38 well into the cover, it is necessary that the can proper be rocked as about fulcrum 35 so, in effect, that portion of the rim of the can shown to the left as viewed in Figures 5 and 8 will be raised against the point 38. During this rocking operation,'of course, the desirability of having member 36 flexible will be apparent so that, without'special attention from the operator, it will follow the canas it is rocked or as its top is pushed to the right in the opening operation.

It will now be apparent it is believed thata reasonably large opening will be providedin the bottom of the can at 35 and that thevent opening 38 will be provided in the top of'the can actmitting air to prevent the oil becoming air bound, or trapped, in the can. Further, it will be notedthat the bottom opening is so made that the oil can fully drain out inasmuch as the final position of can 42 leaves the can in an angularly 'disposed position permitting an assurance that all the liquid will drain from it through the device.-

Throughout my description I' have discussed my device as being used for that purpose which, at present, appears to be the one ino'st desirable for such an arrangement. However, it is believed it will be apparent that my device could be suitably made for use under an y'condition where it is desired to open and drain a sealed container made of sheet metal, paper, or other sheet products. By suitable design my device could be used with cans of square or rectangular section just as easily as with the round, andit might be used to drain fruit juices, or any other liquid from containers just as effectively as it is 7 used for the draining of oil.

This dispenser could also be used as a measur-f ing unit by marking on body 50 the height of the volume of liquid to be dispensed.

The foregoing description and the accompanying drawings are believed to clearly disclose the preferred embodiment of my invention, but it will be understood that this disclosure is merely illustrative and that such changes, in the invention may be made as are fairly within the scope and spirit of the following claims I-Iaving thus fully described my invention, what opening, the combination. of means depressed substantially within the dispenser for supporting the can in tiltable position, and can-puncturing" means mounted on the supporting means within the dispenser in position to cut a pouring-hole in a head of the can whenthe latter is rocked under pressure into contact with the can-puncturing means.

v2. In a liquid-dispenser in which acan is adapted to be rocked under hand-pressure for puncturing a pouring-hole and a venting-hole, the combination with an interior support upon which the can rests in rockable position, and puncturing-means mounted on the sup'port in position to puncture a hole in the lower head of the can, of a flexible support mounted on the dispenser in axial alinement with said puncturing means, and a vent-cutter mounted on the flexible support adapted to form a vent-opening in the upper head of the can, said puncturing means and vent-cutter being operable under asingle rocking movement of the can.

3. In a liquid dispenser in which a can is adapted to be rocked under hand-pressure for puncturing holes in its opposite heads, the combination with an interior support on which the can of the upper head of the can.

4. In a liquid dispenser having an upwardly and outwardly flaring top portion in which a can is adapted to be rocked under hand-pressure, the combination with an interior rest, a transversely extending fulcrum, and an upwardly extending cutter, of a resilient supportmounted at the front of the dispenser, and a downwardly projecting cutter mounted at the free end of thefresilient support, whereby a pouring-hole and a vent-hole are cut in the respective heads of the can when the latter is rocked on the fulcrum.

5. In a liquid dispenser :in which a can is adaptedto be bodily confined and rocked for opening, the combination with a fixed interior support substantially depressed within the dispenser and forming a fulcrum for the can, of a spaced cutter rigid with the support and projecting upwardly therefrom to initially support the can before it is rocked to puncturing position of the cutter.

nation with an interior substantially depressed support having an upper, fulcrum edge partially supporting the can in rockable position, of an up- Wardly projecting cutter spaced from the fulcrum edge and mounted on'the support, and said cutter forming an initial support for part of the can before the latter is rocked upon the fulcrum edge.
